Chapter 5, Problem 9RETC

Explanation of Solution

Zero-address architecture:

It is a stack-based machine and all the operations are performed using values that are stored on the operand stack. Its Instruction set architecture allows the operations mentioned below:

• PUSH M: this instruction pushes the value stored at memory location M onto the operand stack.
• POP M: this instruction pops the operand stack and stores the value into the memory location M.
• OP: this instruction pops two values off the operand stack, performs the binary operation OP on the two values, and pushes the result back onto the operand stack.

One-address architecture:

An accumulator is used in this architecture in order to perform computations. Its Instruction set architecture allows the operations mentioned below:

• LOAD M: this instruction loads the value stored at memory location M into the accumulator.
• STORE M: this instruction stores the value in the accumulator into memory location M...
